SPECIFICATION forming part of Letters vPatent No. 771,704, dated October 4, 1904. Application filed February 23, 1904. Serial No. 194,655. (No model.)

To all whom, it may concern,.-

Be it known that LWALTEE BEINTON, a citizen of the United States, residing in Highbridge, in the county of Hunterdon and State of New Jersey, have invented certain new and useful4 Improvements in Safes or Vaults, of which the following is a specification.

This invention relates to safes or vaults, more particularly to that class thereof known as burglar-proof safes or vaults, an object of the invention being' to provide an improved burglar-proof structure comprisingy an integral body and an integral door, forming what is usually known as an integral 0r Ltwopiece safe or vault.

A further object of the invention is the provision of an integral burglar-proof safe or Avault formed of unmachineable or unworkable metal-such, for instance, as manganese steel-so that it cannot be readily cut or drilled with ordinary tools, with certain improvedv features by means of which those parts thereof which ordinarily might be weaker than the unmachineable integral walls of such safe are reinforced, in consequence of which such parts will equally, if not to a greater extent than the integral walls of such structure, resist burglarious operations and prevent entrance to such safe or vault.

A further object of the invention is the provision of an improved integral burglar-proof structure so organized and constructed that those parts thereof which would ordinarily be weak are materially reinforced, but in such manner that the castings are maintained substantially uniform throughout, thereby to permit the production of superior castings f and so that when the structure is formed of unmachineable or non-workable metal-such,

for'instance, as manganese steel, which is i preferable-and it is desired to heat-treat the y same in order to increase its resisting qualities this may be readily done without impairing or injuring such casting.

A further object of the invention is the provision of an integral burglar-proof safe or vault body with an improved reinforced front, affording increased protection to the joint of the door.

A further object of the invention is the provision of an integral safe or vault body with a reinforced elongated jamie-surface.

A further object of the invention is the provision of an integral safe or vault with improved means for securing the door in its locked or closed position. i l

A further object of the invention is the provision of an improved rotary-door-locking integral burglar-proof safe or vault simple in its construction and operation and effective to prevent the forcing out of the door under burglarious or mob attacks.

A further object of the invention is the provision of an'integral safe or vault embodying a rotary door with coperating locking means formed integral with the door and body and so organized that such .cooperating locking means can be readily machined or worked to obtain superior effectiveness when the structure is formed of non-workable or unmachineable meta1-such, for instance, as manganese steel.

In the drawings accompanying and forming part of this specification Figure l is a front elevation of this improved safe or vault with a part of the door, body, and hinge shown in section. Fig. 2 is a cross-sectional view thereof. Fig. 3 is a vertical sectional view thereof. Eig. 4 is an enlarged partly cross-sectional View of the door. F ig. 5 is a horizontal cross-sectional view of the body.

' Fig. 6 is a vertical sectional view of the safebody looking toward the front.. Fig. 7 is a detail enlarged view of a portion of the front of the body, and Fig. 8 is a detail view of one g'of the locking bolts or members,

Similar characters of reference indicate like @parts throughout the different figures of the drawings i As a preface to a further description of this fimproved safe or vault it is to be understood that certain of the improved features herein referred to could be used with safes or vaults formed of other material than manganese steel. and with manganese steel whether the same be heat-treated or not; but as manga-A n'ese steel has been found to give the best results in burglarfproof structures and superior results when the castings formed thereof are heattreated,and thereby toughened,the pres- IOO ent improvements are particularly well adapted for such a structure. rlhe superior effectiveness of a heat-treated manganese-steel safe, owing to the inherent quality of such heattreated metal, will, it is believed, be very materially increased by the reinforcing qualities and effectiveness of the several improvements herein shown and described; but, as stated, it is to be understood that certain of the improvements about to be described are of considerable Value independently of the character of the material of which the structure is formed, although, as stated, they are particularly designed and adapted for use with unmachineable-metal integral safes or vaults heat-treated or otherwise, but preferably heattreated.

This improved safe or vault comprises in the preferred form thereof herein shown and described an integral safe or vault body 2, shown, preferably, of arched formation throughout-that is, having resemblance to an oblate spheroidgprovided with a circular doorway 3, having located around the same a forwardly-extending reinforcing bead or projection of metal 4 integral with such body. The body also has an interiorly-located inwardly or rearwardly projecting' fiange 5 of considerable length or depth, forming between it and the walls of the body a recess 6, whereby substantial uniformity of the metal around the jamb is preserved and which fiange is shown connected with the walls of the body by a series of ribs 7, forming braces shown integral with the fiange and bodywall. These braces are provided to stiffen and give greater rigidity to the jamb and to the inwardly-projecting fiange partly forming the same, which flange is, as stated, of great depth or length, the length of the jamb-surface being by means of the present organization very materially prolonged, so that a jamb or joint surface around the door of very great depth is provided. It is well known to those familiar with burglar-proof ystructures that the greater the depth of the jamb the greater is the resistance of the safe to burglarious attacks, since great depth of jamb necessarily increases the surface over which the shocks of an explosion must be distributed, so that the effectiveness of such an explosion is materially decreased. By providing the ribs cast integral with the body and flange such jamb-surface may be materially increased in depth without the formation of a large mass of metal at this point, so that not only may a superior casting be furnished free of internal strains and cracks, but when it is desired to heat-treat the casting this may be successfully done, it being well known thata uniform casting, particularly when formed of manganese steel, can be more readily-and effectively heat-treated. Infact, when formed of manganese steel it cannot be properly heattreated at all unless it is substantially uniform.

This uniformity is, as stated, a desirable feature, even though the casting should not be heat-treated, for a much better casting may be obtained by preserving a substantial uniformity of metal at all points, since this obviates the setting up of internal strains within the casting during the casting operation. The provision of the braces or ribs therefore not only enables the furnishing of a casting having substantial uniformity around the doorway, but enables the provision of a materially elongated or prolonged jamb-surface integral with the casting, a very desirable object.

-In the present instance the bead 4 is so formed that there is a depressed part or grinding surface 8 contiguous to the joint and which is fiush, or substantially so, with the contiguous outer surface9 of the door 10, such surface Sand 9 being ground so that one does not project beyond the other to any considerable extent when the door is firmly seated in its jamb, and which feature forms a part of the subject-matter of a contemporaneouslypending application, Serial No. 175,161, filed September 30, 1903, of myself and Walter Gaston. This same formation is obtainable and desirable even when the door-bead is dispensed with by projecting the safe or vault front beyond the door-that is,so forming such front that a projecting wall is provided beyond the annular surface terminating the joint, as shown in and more particularly forming part of the subject-matter of my contemporaneously -pending application, Serial No. 212,924, filed June 17, 1904. This bead is shown reinforced. In the present instance the bead has located in it at equal distances apart around the same and adjacent to the door-joint a series of members 49. These members are interlocked with the bead during the casting of the body, so thatto all intents and purposes they are integral therewith. They may project beyond the surface of the bead or body of the casting and then ground ofi' flush, or substantially so, with the surface of such casting, as in the present case, such inserts projecting more or less, as occasion may require, or if for any reason it is desirable to leave them appreciably project beyond the surface of the` casting this could be done, as shown in the said application hereinbefore referred to. They are shown of wedged or dovetailed construction fitting into corresponding pockets or recesses in the beads, and thus held against displacement. These members are formed of hard metal, preferably of chrome-steel, and are located in IOO TIO

position to receive the blows of a sledge or shown they have their outer surfaces exposed and preferably substantially flush with the metal of the body contiguous thereto, the inner or bottom faces thereof being, when these parts are located in a bead or a surface which projects beyond the joint or surface of the door contiguous thereto, preferably substantially iiush or in line with the termination of the joint at the outer end thereof. This organization is particularly well adapted when the safe-body is formedof manganese steel, which is very tough, but which under some conditions may permit the peening of the metal adjacent to the joint, owingv to the yielding' quality of such metal. By the provision of these hardmetal members, however, even the possibility of peening the metal at the joint is prevented, since this chrome-steel or analogous metal has no tendency whatever toyield, but owing' to its hardness will break the sledge or tool used on it. The provision of the bead, however, owing to its yielding' characteristics, insures a metal-to-metal lit of the jamb and door-joint surfaces and the preservation of a tight joint at all times, for the reasons set forth at length in the patent granted to Henry D. Hibbard November 27, 1900, No. 662,429- that is to say, should an explosive charge be placed on the joint the result would be to force the metal of the door inwardly at this joint, and consequently outwardly at its edge or joint surface, in a somewhat similar manner to which a piece of putty is caused to spread at its edge by the insertion of the thumb into the body thereof adjacent thereto, and as this action of the door-metal takes place the metal of the bead adjacent thereto is likewise forced radially or laterally to conform to the bulging portion of the door edge or joint surface, it yielding with the metal of the door, and thus preserving a metal-to-metal contact and a tight joint under such explosive charge, manganese steel having this peculiar yielding quality, it yielding, owing to its toughness, rather than cracking. ln some forms of safes, however, it might be practicable to use these hard-metal reinforcing members around the doorway even though the bead was dispensed with, especially when the form of the safe around the doorway would permit a peening action of the metal. rllheyv are, however, of superior efficiency in connection with such bead or with a safe or vault front which projects beyond a depressed portion or grinding surface terminating the joint. Should the structure be a large vault and have several joints, then these inserts could be'located along each of such joints in the same way they are located around `the jamb. These inserted members, which are shown with their outer faces ll exposed and substantially flush with the bead, are, as stated, of wedge-shape formation, the larger area of each being at the bottom. Owing to this pen culiar arrangement, should the blows of the sledge or other tool be directed on the manganese steel adjacent to these members instead of directly on the members such blows will, nevertheless, be received by the members and not transmitted to the manganese steel to any considerable extent at the bottoms of such members, for the reason that as the members are of larger areas at their bottoms or inner portions-in other words, spread out--the efficiency of any blow directed on the mang'anese steel or bead adjacent to such inserts would be received from such manganese-steel portion directly onto the enlarged or spreadout inner surfaces of the members, so that the effectiveness of the blows to secure a peening action of the manganese steel would be materially interfered with.

I believe I am the lirst to provide a means formed of a metal composition different from the metal composition of which such body is formed in the form of a plurality of inserts located in the front of a safe or vault body adjacent to the joint or jamb-surface thereof during the casting of such body for the purpose of resisting the action of sledges or analogous tools to prevent the peening ofthe metal around such joint, and therefore whether this means be in the form of a series or a less number of sections located side by side entirely around the jamb it" is believed to be within the scope of my invention. Vhen this means is so disposed that its outer face is exposed to form a striking-surface and directly receive the blows of a sledge or other tool, this means could be in some structures in the form of a ring', since it is not for the purpose of acting as a steel band to hold the metal under compression to primarily prevent the use of wedges, as in the present form of safe. The door being circular, it is ground to a matching lit, and therefore it is not practicable to insert a wedge unless the metal is lirst peened to permit this, and by the provision of this improved reinforcing means this peening is prevented, since the means is so located that the surface of the metal at the joint cannot be forced to yield under the action of a Sledge or other means. The embedding of a ring in the body of the safe a considerable distance below the surface merely to act as a compression-band to prevent wedging would leave a certain portion of the metal outside or in front of the band, which under the action of a Sledge could be peened, and if once peened to afford even aslight opening it could be further wedged open notwithstanding such band, sufciently atleast to permit the insertion of asmall quantity of nitroglycerin, a few charges of which, if one was insufficient, would offset such band very quickly, and especially could this be readily done if the joint wereasquare joint, so that the parts could not be ground to a matching fit. In the present case the use of a ring for the mere purpose of increasing the tensile strength would not be of any advantage or have any IOO value, since every square inch of a casting of manganese steel is equal to the strength that would be present in a safe formed of other metals, even with the rings in place, so that in the manganese-steel casting there is without the rings the same high measure of strength; but by adding the inserts a barrier is formed against compression by hammer or other blows. Furthermore, the use of a ring, even when so located as to be effective to prevent the peening of the metal adjacent to the jamb, is not as advantageous and does not give the superior results which are present from the use of separate inserts or sections in that the expansion and contraction of the ring during the period of casting would be likely to set up strains in the casting, owing to the arch of the ring, while in the case of separate inserts there is no tendency whatever to cause such strains. Moreover, by using the series of inserts the possibility of attack in any form is more difficult, since each insert is indel'iendent of the other and firmly incased and held by the umnachineable or manganese steel, whilein the case of a ring it would only be possible to have the casting incase the inside and outside diameters or surfaces of the ring, which would not give the same security against attacks as separate or independent inserts would. From the foregoing it will be seen that these hard-steel inserts located in the front of the body during the casting thereof are so designed that when the body is in process of casting' the fluid manganese steel completely envelops the inserts, which are larger inwardly than outwardly, and therefore the exposed part, which is merely on the surface, is of less area than the baseor inner surface of the inserts. The inserts are therefore firmly lixed or held in position, making' it impossible to loosen or remove them from their position except by the destruction of the manganese steel, with which they are entirely enveloped, and these inserts are of such composition as will be proof against and withstand enormous compression, thereby insuring the joint against any possible peening effect by stretchingl of the metal at the door-jamb by sledging or otherwise and will thus wholly prevent the admission of fluid explosives. These inserts also have several functions to perform in assisting' to make the safe-bod y casting a success from the casting standpoint, thereby insuringa superior safe-body casting to the castings heretofore made for this purpose, not only in their value from the point of hardness which they present on the surface of the jamb, but they give very great assistance toward making the main body of the safe-casting solid and perfect, because of their tendency to solidify the molten metal by cooling' or absorbing the heat at the point in the casting where the greatest amount of heat accumulates and is retained during the pouring of the casting and also during the cooling of the same to the proper degree of heat preparatory to the toughening or treating process.

rl`he door 10, which, like the body` is of integral formation, preferably comprises a body 13 and an inwardly or rearwardly extending fiange 14, whereby the uniformity of the metal in the door is likewise maintained, insuring a better casting' even though such casting be not heat-treated and insuring a better heat treatment of the casting when the door is heat-treated and by which organization an elongated or prolonged joint-surface is obtained without the necessity of forming the door of a great mass of metal throughout. llt is to be understood, however, that the improved features herein so far set forth or to be set forth are of practical value independently of the particular form of door. The door, which in the presence instance is arotary one and, like the jamb, is of conical formation, is provided with a series of projections or lugs 48, located around the same and integral therewith, forming' between them and an annular portion 15 of the door an annular recess 16 for the reception of a similar set of lugs or projections 17, integral with the body around the jamb-surfaces thereof and corresponding with the projections or lugs 48 of the door, the projections or lugs on the jamb being located in the present instance substantially midway of the depth of the jamb and provided with beveled or tapered inner corners 18 to insure the proper seating of the door in the jamb. rlhe side faces 19 of the jamb lugs or projections are straight, as likewise are the side faces 2O of the lugs or projections formed on the door, so as not to interfere with the passage of the door-lugs into position to be rotated back of the lugs on the jam b. The outer and inner surfaces 21 and 22 or front and back surfaces of the projections on the door and the same surfaces 23 and Q4 on the jamb are ground to a matching' lit. This is not necessary with the side surfaces of the projections, in consequence of which it is practicable from a commercial standpoint to form these projections integral with the body and door when the same are formed of unmachineable or unworkable metal-such, for instance, as manganese steel. By this organization it will be seen that the lugs on the jamb and door are not located one in front of the other in the form of tapered lugs or threads, as is usual in rotary-door safes, but that all of the lugs are located side by side entirely around the jamb and door, respectively, and are of the same depth and having plane meeting faces instead of inclined or tapered ones, as heretofore. The lugs in the present instance extend depthwise of the jamb and door instead of circumferentially thereof. The inner face 22 of each lug on the door has a positive bearing on the inner face 24 of its corresponding lug formed on the jamb, such meeting' faces IOO IOS

being straight, as just stated, the drawing of the door tightlyt itsseatbeing obtained by the beveled or tapered corners of the jamb-lugs. By this organization the grinding of the door to its seat is not interfered with, as is the case where the locking means comprises threads or tapered lugs, so that the grinding of the door by partially rotating the same to a matching fit with the jamb-surface is permitted. These lugs or locking-surfaces, any desired number of which may be used, arelocated in sets, each set comprising a lug carried by the door and a lug carried by the body, designated herein -as a door-lug or locking-surface and a body-lug or locking-surface, one of each set being shown provided with -a beveled or tapered edge or corner,which in some forms could be on the door-lugs instead of on the body-lugs, as shown herein, or on both. By forming them on both a quarter of an inch bevel on each will give a half-inch space to start the grinding operation. By forming the lugs with straight or plane meeting or engaging faces parallel to the plane of the door instead of with tapered or inclinedly-located meeting surfacesthere is no tendency of the door to work itself back, as is the case with a door which is drawn to its seat by tapered surfaces or screw-threads formed either by the location of the lugs or threads in a plane inclined to the plane of the door or by lugs having inclined or tapered surfacesthat is to say, when the door is drawn to its seat by the use of tapered surfaces or threads or lugs located inclinedly to the plane of the door the wedging action which is imparted tothe door to bring it to its seat firmly in the jamb is such that under vibration the tendency of the door-lugs is to slip back on the inclined or tapered body-lugs, and so form a space at the joint around the door for the insertion of nitroglycerin.

It is believed that it is a recognized fact that an integral rotary door locked to its seat by integral lugs is one of the strongest doors that could be made; but heretofore, owing to the backlash which is aiways present in a door of this kind, permitting the joint to be opened, it has not been found practicable to make an integral safe of this kind that could not be opened within a burglarious time, and this has been largely due to the factthat the lugs or threads used to lock the door in place not only were not integral with the door and body, but had tapered meeting faces throughout their engaging portions, so that when the door was locked to its seat the strain was such that its tendency was to rotate back, this being prevented only by the locking-bolts or other means which were used to prevent the rotation of the door and which when automatically controlled did not fit with such precision as would prevent aslight backlash. Even though this backlash was but slight it would be suflicient to start the door out of its jamb, owing to the tapered or inclinedly-located locking-s urfaces, and as the door has a tapered jamb-surface the space formed around the door would be in proportion to this taper. The greater the taper the greater the opening of the joint. In my safe, however, when the door is firmly seated and rotated to its final position there is no tendency of the door to rotate backward, or to its initial position, since the meeting surfaces of the door and body lugs are plane or straight faces. In this improved safe the beveled corners of the body-lugs on theirfengagement with the plane faces of the doorlugs during the first part of the rotary movement of the door pull it inwardly andflrmly into its seat until there is a metal-to-metal tight joint around the jamb, and then on the further rotation of the door the plane surfaces of the door-lugs and body-lugs engage throughout their entire area, so that there is no longer any appreciable tendency of the door to rotate backward, and consequently there is no backlash. Even if the door were rotated a short distancethe grinding-surfaces around the door and jamb would still be flush with each other. In fact, the door could be rotated the entire area of the plane surfaces of the lugs and yet the door would not be thrown out or project beyond the grinding-surface on the body. whereas when the lugs have tapered surfaces or are in the nature of threads or located inclinedly to the plane of such door when the door is rotated backward even a small amount it is thrown out in proportion beyond the jamb, as hereinbefore stated, and owing to the tapered formation of the door and jamb opening up the joint. From the foregoing it will be seen that even if the door of this improved safe is rotated backward the joint would not be opened up until the plane faces of the door-lugs passed away from the plane faces of the body-lugs, so that the door would have to be rotated the full area of the plane surfaces of the lugs, which would of course necessitate that the heads of the bolts used to prevent rotation of the door be entirely broken o, before any space at the joint could be obtained. Thus it will be seen that each lug that has a beveled face performs two functions, one a drawing-in function during the first part of the rotary movement of the door and so long as such beveled face is in engagement with the plane face of the door-lug, and then a holding or true-locking function during the time the plane faces of the lugs are in engagement as distinguished from a continued drawing-in action, which is present when the lugs have tapered surfaces throughout their entire area or are in the form of threads or located inclinedly to the plane of the door. When the lugs are formed with beveled or inclined corners, as set forth herein, they not only assist in the seating of the door, so that it may be more easily seated, but such construction also assists in properly IOO locating the door to facilitate its withdrawal after the plane meeting faces are disengaged. To prevent the door from being rotated and withdrawn after the same is properly seated, radially-acting bolts 25 are; provided, which inthe form shown are thrown outwardly by gearing controlled by a tapered spindle 26, projecting through the door. This spindle is provided with a collar 27 or other means secured on the tapered end thereofl at the inner side of the body of the door to prevent its being withdrawn, the tapered formation thereof preventing it being forced inwardly from the outside. In the form shown the iiange of the door is provided with bolt-openings 28, soft-metal inserts 29 being cast therein, such inserts having threaded portions 30 coperating with threaded shanks 31 of the bolts, the bolt-heads 32 being connected with the shanks by a slotted connection, (see Fig. 8,) so that the shanks may turn relatively to the boltheads to thereby withdraw or move the bolts radially in the angular openings 5() formed in the inserts. These bolts project into bolt openings or recesses 33, located in the jamb, and, if desired, the bolts and recesses could be of tapered formation at certain parts thereof to assist in a tighter wedging of the door within its jamb. In the present instance the inner ends of the bolt-Shanks 31 are shown supported by a bracket 34, secured to the back plate 35, which back plate is secured to the door by means of soft-metal inserts 36, located within the door-fiange and into which the bolts carried by the back plate extend. The inner ends of the threaded bolt-Shanks 31 j are provided with beveled gears 37, meshing with a beveled gear 38 on the inner end of the spindle 26, so that on the turning of such spindle the bolts will be thrown outwardly or Withdrawn, as the the case may be, the manipulation of such spindle and of the bolts being controlled by combination-lock mechanism. (Not shown.) It will be obvious that other means of throwing or withdrawing the bolts may be provided-that is to say, this may be done automatically, as by means of the usual automatic time-lock, thus doing away entirely with the use of even a single spindle through the door-and that a different mode of operating the same by means of the spindle could be used, if desired, and without the necessity of supporting it in the back plate. To support the door for movement into and from its seat and for rotary movement to permit it to be locked and unlocked within its seat, the hinge 40, which may be of the usual crane formation having the usual adjusting' means, pivotally carries a ring 41, having an annular recess 42 at its front. The door is shown provided with a forwardly-extending iiange 43, which may or may not be integral, onto which is shrunk in the present instance a ring 44, which fits within the ring 41, carried by the crane-hinge. To the ring 44 a plate 45 is bolted or screwed, such plate fitting the annular recess 42 of the ring 41. The play of the door in the crane-hinge ring 41 is prevented rearwardly by the plate 45 and forwardly by the door itself. For rotating the door within the ring 41 the ring 44 is provided with a toothed segment 46, in mesh with a pinion 47, mounted on a spindle carried by the crane-hinge 41 and which spindle is in position to be engaged by a crank, and in rotating the pinion the door will be rotated to carry its locking lugs or projections back of the locking lugs or projections on the jamb.
